概要

JIRA Data Center cluster replication relies on nodes being recorded in a database and also receiving and sending updates. The Health Check confirms that the replication is working in the entire cluster. If an active node is not responding, the other nodes are going to be reporting warnings and the one with the error will report a critical result.


Understanding the Results

アイコン結果What this means
The health check passed successfully.Node replication within the cluster is working.
The node <node> is not in the database.

The node does not appear to be in the database however does exist within the replication cache, or the node is unresponsive.

The node <node> is not replicating.The node is not replicating information to the cluster - it exists in the database but not the replication cache.


トラブルシューティング

問題提案
The node is not in the database.

Restart the affected node. Prior to doing so, it is recommended to collect some thread dumps as per Generating a Thread Dump as these can be sent to support with the data below.

The node is not replicating due to a network condition.
  • There may be a firewall or network condition blocking communication between the nodes. Check the logs on each of the nodes for exceptions relating to network connectivity.
  • JIRA Data Center can be configured to use TCP multicast to communicate between the nodes. Check the configuration in the cluster.properties file and review the Install Guide more information.
  • If you are using multicast, to check the current multicast address in use, run the command: netstat -g on each of the nodes.
  • It is not expected that a firewall would be used between JIRA Data Center nodes.
  • Each server needs to be able to resolve its own host name correctly. Specify the hostName property for the cacheManagerPeerListenerFactory in the cluster.properties, following the instructions in the Install Guide.

A request JRA-43380 - Getting issue details... STATUS has been raised to have these configuration options documented.

The node is not replicating due to nodes being offline.Check the status of each of the other nodes, specifically if they are online and responsive.
